the other night I found a water district analysis which dated a few years back when they did some larger planning. There were two metals which were really high, the other stuff was just normal. I will dig it out again.

Your water analysis is missing 1 major ingredient, BUTTER. I would have thought there would be a big yellow triangle for high butter concentration. I think this analysis basically says this water is terrible and you should not kite in it

This attached link if for the water quality for raw and treated drinking water in Benicia. It has some limits on various contaminants and might be useful for helping to decipher the tests from the Pond A4 report.
